Conductor
Stranded compacted circular copper or aluminium conductors. All internal interstices of trie conductor rilled with water blocking compound which is specified to prevent ingress of water through conductor during storage, handling, installation and operating of the cable.

Insulation Screen
Extruded Semi-conducting compound. Minimum thickness 0.5 mm and the maximum volume resistivity of 5000 ohm-cm at 20°C and 25000 ohm-cm at WC The screen is tightly fitted to insulation to exdude all air voids and can be easily hand stripped on site.

Conduction Water Blocking Layer
Semi-conductive water blocking tape provided over the insulation screen which will swell up under the influence ofmoisture or water.
